SKYLIGHT-OPENER.

Specification of Letters Patent.

Application filed December 24, 1904. Serial No. 238,234.

To @ZZ whom it may concern:

Be it known that I, GEORGE BICKELHAUPT, a citizen of the United States, residing in New York" city, borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Skylight-Openers, of which the following is a full, clear, and exact specification.

My invention relates to an improved device for opening skylights in which the means for locking the same in open or closed position and of releasing the lock are controlled by the raising means.

The objects of my invention are to produce a simple and stron(r device which can be used as well with hipped skylights as with flat skylights; to use the lifting-bar not only for the purpose of lifting the skylight, but also as part of the locking means; to support and guide said bar in a pivoted block which carries the locking device, and to control the said lock by the same cord which lifts the skylight.

Other details of my invention are fully illustrated in the accompanying drawings, illustrating one form in which I have embodied my invention, wherein- Figure 1 illustrates in side elevation my improvedidevice applied to a skylight which is partly in sectionand is shown in raised position. Fig. 2 is a top view of the bracket, pivoted block, and locking device, the block being tilted with respect to the bracket and Fig. 3 is a front elevation of the bracket, pivoted block, and locking means.

I have illustrated my device as applied to a hipped skylight 1, hinged to a curb 2, but my improvements render the device equally applicable to aiiat skylight.

Attached to the inside of the curb` 2 isa bracket 3, carrying inwardly-projecting ears 4 5, in which is mounted pivot 6, which furnishes abearingfor the pivoted block 7. This block is provided at its outer end with a passage-way 8, extending through the block from top to bottom and which is just large enough to receive the lifting-b ar 9 and permit the same to move freely therein without any unnecessary play.

The pivoted block 7 permits the lifting-bar to freely swin as the skylight is raised. This is a valuable eature and contributes greatly to the efliciency of the device. In applying the device to liat skylights which are incline toward the front and wherein when the skylight is lifted to a horizontal position its forllocated therein at convenient points.

ward end will be outside'of a verticalline drawn through the forward end ofthe curb this pivoted block will be of great assistance, as it will permitthe lifting-bar to be applied to the front of the skylight, where it will have the greatest lifting effect.

Lifting-bar 9 is bent inwardly `near its upper end, as at 10, so that the body of said bar will assume a substantially vertical position when the skylight .is closed. This bend will be useful when the device is applied to a flat skylight to prevent extreme ytilting of the block. It also enables said block to be made shorter.` Bar 9 at its upper end is attached to the forward end of skylight 1 `by a pivot 11, journaled in lugs on a bracket 12, and this pivot is through bend 10 offset from the center of bar 9. At its lower end bar`9 is bent at 13 in the opposite direction to bend 10 and to a less extent. The extreme lower end of said bar carries a pin or bolt 14, which projects to one side thereof sufficiently to provide a bearingV for sheave 15, housing 16, and hook 17.

I will now describe the means whereby the lifting-bar is locked in its adjusted position.

On the right-hand side of the pivoted block -7 is a lever 18, mounted to freely swing on a pin 19, carried by lugs 20, that are fixed to block 7 At its forward end this lever 18 carries a stop 21 of L shape, mounted therein so' as to turn and having an arm 22, which passes through openings in the pivoted block 7 and traverses the passage-way 8 in saidblock.

Lifting-bar 9 is provided with openings 23, These openings determine the points at which the skylight can be locked in Aposition and pass through bar 9 from side to side, being of such a size as to receive stop-arm 22. One of them should be so placed that the skylight will vbe locked when closed. j

Rod 24 passes through block 7 about midway between the bearings 20 and armv 22 and is designed -to pull the stop-arm 22 at all times toward lifting-bar 9, so as to enter any desired hole therein. To accomplish this, the said rod has a threaded end-upon which is screwed nut 25. Between this nut and the block 7 thek rod 24 is encircled `by a spiral spring 26. At its opposite ends this rod 24 has a portion thereof bent rectangularly, producing elbow 27, which passes through a hole in lever 18 about midway between bearing 19 and L-stop 21. y V- The force of spring 26 tends to pull that IOO IIO

end of lever 18 which carries L-stop 21 constantly toward the block 7. The tension of the spring 26 may be increased or diminished, as desired, by turning nut 25 oneway or the other. The opposite or, as it might be called, the free end of the lever 18 has Xed upon it an outwardly-projecting U- shaped strap 28, closed at its outer end and supporting bearings 29 and a sheave 30, over which passes the lifting-cord 31, which is held in place by the closed end of said strap 28. Suitable pressure upon sheave 30, through cord 31, will rock the lever 18 and cause arm 22 to emerge from that one of recesses 23 of bar 9 in which it may be, and the bar 9 may then be adjusted to a new position.

The skylight is raised in the following manner: Lifting-cord 31 is attached to the lower end of bar 9 in any suitable manner-as, for instance, hook 17, the closed end of which encircles pin or bolt 14 between sheave 15 and bar 9 and the open end of which is hooked into a loop in the cord 31, as shown by dotted lines in Fig. l. From hook 17 the cord passes up over sheave 32, mounted on shaft 6 to the left of pivoted block 7, down again and under sheave 15, then up, passing behind sheave 32 and between that and bracket 3 and over sheave 34, which vis mounted in the upper part of bracket 3. The cord then passes over sheave 29, by which the locking mechanism is controlled and which is pur osely placed to one side of sheave 34 rat er than directly beneath it, so as to increase the control over the locking mechanism. The cord then passes down within reach of a persons hand.

A suitable stop--such as cotter-pin 35,

which passes through bar 9-may be emloyed to limit the height to which the skyight may be raised.

The operation of my device is very simple and will be easily understood from the foregoing description of the mechanism. The skylight being closed will be locked in such closed position by sto -arm 22 having entered the up ermost ole 23 in bar 9, in which it is he d by rod 24, spring 26, nut 25, and elbow 27. When it is desired to raise the skylight, the lifting-cord 31 is held taut and ressed toward the left, whereupon lever 18 will be rocked and stop 22 withdrawn. A

' continued pull upon cord 31 will then raise the skylight to the desired position, the stop 22 having been in the meantime restrained from entering the intervening holes 23 by reason of the continued pressure upon sheave 30. The cord is then held to the right and the skylight raised or lowered until the stop 22 enters the desired hole 23, where it will stay until released.

It is obvious that I have shown but one form of a number in which my invention may be embodied, and numerous changes may be made therein without departing from my invention-for instance, the articular manner of locking or unlocking t e lifting-bar or the form of said bar may be changed, &c. The material which I have employed for all parts of my device excepting the cord is iron but other material may be used.

What I claim, and desire to secure by Letters Patent, is-
